Alex and Calvin are working on understanding those strange plasma balls you see in science experiments. Here are some links:
PLASMA BALLS. You can buy one.
“History”:http://www.eng.utah.edu/~kier/history.html. History of the plasma ball. It’s actually a kind of Tesla Coil. Didn’t know that. So on to this fellow Nikola Tesla. Amongst other things, Marconi (I though he invented radio) actually had his patents invalidated and Tesla is the true inventor of wireless and radio.
“Theory”:http://www.eng.utah.edu/~kier/theory.html. The theory on how it works. It’s actually kind of complicated.
“Nikola Tesla”:http://www.neuronet.pitt.edu/~bogdan/tesla/. A basic bio on Nikola Tesla. He was Serbian.
“Nicola Tesla”:http://ohoh.essortment.com/nicolateslaalt_rvmk.htm. Most readable short biography.
